Application led September 7, 1909. Serial No. 516,570.

To all whem 'it may concern:

Be it known that I, MARK A. Ross, a citizen of the United States, residing at Chicago, in the county of Cook vand State of Illinois, have invented a certain new andl useful Improvement in Locomotive-Head lights, of which the following is a specificatlon.

My invention relates to locomotive head lights.

It is illustrated in the accompanying drawings, wherein- Figure 1 is a cross section through the Case, Fig. 2, a front view of the same, and Fig. 3, a detail cross section on the line 3-3 of Fig. 2.

Like parts are indicated by the same letter in all the gures.

A is the case, B a reflector therein, C the front ofy the case which is provided with a large hole inside of which is the sleeve D approximately in line with the reflector.

E is a short tube having the glass F at its outer extremity, and the bead G whereby it is stopped against the face C of the ca se when its inner portion enters the thimble.

H, I-I are handles on the outer part of the tube whereby it can be manipulated.

J, J are a series of fingers projecting from the tube and adapted each to be received under one of the spring grips K, K which are secured to the front .C of the case A and are downwardly curved toward their outerends so as to leave in each a kind of recess into which the linger is sprung so as to be gripped. l This is only one of the various means which might be employed to secure the device' in this position.

In locomotive headlights it'is frequently necessary to clean or polish the refiector and also to clean, polish and sometimes replace the glass and' its holding part. Where, asl

is usually the case, the glass holding part is hinged to the case which contains the reflector, it hangs, when thrown back on its hinges, in such a way as to injure the case and draw the parts out of their proper relation. Moreover, it is not easily detached for repairs or cleaning. It is much more desirable to have it bodily removable and this is what my invention permits. The tube containing the glass is inserted into the thimble which furnishes a long bearing for it, is then turned by the handles in the direction indicated by the arrow in Fig. 2 until the fingers are forced under the grips,

.is an outwardly turned li wheregpon the parts are held securely against the jarring of the locomotive, in the position shown in Fig. 1.

The reflector B is preferably adjustably supported within'the case A as follows :,L

of the reflector, M a cra le to receive the lower part of the rim of the reflector, N N screws through the li whereby the reflector is secured to the cradrle, O the base, P arms aboutthe edge v connecting the base and the cradle. The

base is mounted on the slide Q which is received in' slots in the bars R R mounted on` the vbottom of the case. The side of the case is preferably in the shape of a door. The reflector can be moved in or out in the proper osition by moving the slot Q in the bars R I claim:

31. In a locomotive headlight, the combination of a reflector with an inclosing case therefor having an opening in the frontthereof, a cylindrical sleeve about said opening and in line with the rim of the reflector, a tube having a glass at its outer end, a stop to limitA its motion into the sleeve, and a series of interlocking devices A-on the tube and the case whereby the parts are secured together.

2. In a locomotive headlight, the combination of a reflector with an inclosing case therefor having an opening in the front thereof, a cylindrical sleeve about said opening and in line with the rim of the reflector, a tube having a glass at its outer end, a stop to limit its motion into the j sleeve, and a series of interlocking devices-on the tube and the case whereby the parts are secured together, the sleeve projecting inwardly from the front of the case.

3. In a locomotive headlight, the combination of a reflector with an inclosing case therefor having an opening in the front thereof, a cylindrical sleeve about said opening and in line with the rim of the reflector, a tube having a glass at its outer end, a stop to limit its motion into the sleeve, and a series ofA interlocking .devices on the tube and the case whereby the parts are secured together, said interlocking devices comprising each a spring portion with which the other engages.

4.` In a locomotive headlight, the combination of a reflector with an inclosing case therefor having an opening in the front thereof, a sleeve about said opening and in line with the rim of the reflector, a tube having a glass at its outer end, a stop to limit its motion into the sleeve, and a series of interlockin devices on the tube and the case whereby ghe parts are secured together, said interlocking devices consisting each of a sping grip onthe case and a finger on the tu e.

5. In a locomotive headlight, the combination of a reflector with an inclosing case therefor having an opening in the front thereof, a sleeve about said opening and in line with the rim of the reflector, a tube having a glass at its outer end, a stop to limit its motion into the sleeve, and a series of interlocking devices on the tube and the case whereby the parts are secured together, such tube and glass being bodily removable from the case.

6. In a locomotive headlight, the combination of a reflector with an inclosing case therefor having an opening in the front thereof, a sleeve about said opening and in line with the rim'of the reflector, a tube slidably mountedt in said sleeve and havin a lass at its ou er end, a series of interlocking evices on the tubey and the case whereby the parts are secured together.

7 In a locomotive headlight, the combiing a glass at its outer end and a series of. i

interlocking devices on the tube and the case 'whereby the parts are secured together, the p sleeve projecting inwardly from the front of the case.

8. In a locomotive headlight, the combination of a reflector with 'an inclosing case therefor havin an openin in the front thereof, a c linrical sleeve a out said opening and in ine with the rim of the reflector, a tube havin a glass at Aits outer endand a stop to limit its motion into the sleeve.

9. In a locomotive headlight, the combination of a reflector with an inclosing case 'therefor havin an opening in the front thereof, a cylin rical tube havin a glass at its outer end adapted to be-slida ly mounted within said opening and a series of interlocking devices on the tube and the case whereby the parts are secured together.
